说明：  利用Lumerical FDTD对光纤进行仿真，对单模光纤进行初步的仿真(Using lumerial FDTD to simulate the optical fiber and the single-mode optical fiber)

C++递归调用，4个整数用四则运算算24(C++ Recursive calls, with four integer arithmetic operator 24)

说明：  LLC软开关，电压闭环控制，可以通过示波器观测到通过开关管的电压和电流波形，清晰地观测到开关管实现了零电压开通(LLC soft-switch voltage loop control)

InSAR是一种极具潜力的新型空间大地测量方法，但它也有其固有的限制，特别是受到大气层延迟（对流层延迟、电离层延迟等）、卫星轨道误差、地表状况和时变去相关性等影响，很容易导致InSAR图像解释错误，而InSAR数据本身无法解决所存在的上述问题。而GPS可以精密定位，可以较为精确地确定电离层、对流层参数，是当前应用最广泛的一种空间大地测量手段。-InSAR is a potential new space geodetic methods, but it also has its inherent limitations. in particular by the delay in the atmosphere (troposphere delay, ionospheric delay, etc.), satellite orbit errors, Surface conditions and time-varying correlation to the impact of such very easily lead to wrong interpretation of InSAR image, InSAR data and by itself can not solve the above problems. GPS precision positioning can be more accurately determine the ionosphere, troposphere parameters, is the most widely used as a means of space geodesy.

说明：  在 matlab 开发平台上，首先进行数据平滑处理，再采用快速傅里叶算法在频域进行 滤波和积分处理，得到重要的速度和位移指标参数，(On the matlab development platform, the data is smoothed first, then the FFT algorithm is used to filter and integrate in the frequency domain, and the important parameters of velocity and displacement are obtained,)
